gate resistors for 1SP0635 when driving a 1MBI2400VC-120P

Posted by: n.werner@m-pulse.eu on

Hello,

We are using a 1SP0635 gate driver to drive a Fuji 1MBI2400VC-120P. Due to availability problems we purchased gate drivers _without_ any gate resistors. Could you name recommended gate resistors for the aforementioned combination?

Best Regards

Norman Werner.

Dear Norman

Thanks for approaching us.

First, please make sure the gate driver you purchased is for 1200V voltage class.

Second, you can refer to "1SP0635x2xx-1MBI1600V-120P" datasheet as the start point to find suitable gate resistors for your system. Rg,on is 3R, Rg,off is 0.5R.

Here is the link to the datasheet "https://www.powerint.cn/sites/default/files/documents/1SP0635x2x1-1MBI1600VC-120P.pdf"

Note: this is a dedicated driver for 1MBI1600V-120P, and here is only a recommendation of a reference that you can work on for your target IGBT
